<Basic knowledge of the UPS power supply>
1.ups must have appropriate margins on power options, fully considering power factors, and the sum of the power of all electric devices must not exceed 80% of the UPS power. If the load is selected for the 800W load, the power should be purchased more than 1000W.
2.ups should avoid frequent booting, shutting down, preferably in the power-on state for a long time. When the load is turned on, it should be performed one by one, it is best not to boot at the same time.
3. The newly purchased UPS is supplemented with the battery before use, because the battery is constantly discharging during the sales process, and its capacity has a large part of the capacity being consumed. If it is not replenished in time, it will not only affect normal Use, will shorten the battery life. The battery replenishing method is to connect the battery in series to charge according to the specific method provided by the battery usage. It is generally charged with constant voltage, each battery control voltage is 2.30 ~ 2.35V, and the initial current should not exceed 0.25c5a to calculate the specific value), so as not to burn bad batteries, the charging current is unchanged for 3 hours. That is, sufficient, can be put into use, the charging duration should be 12 ~ 24 hours.
4. If the city is in normal power supply, the UPS has no work, and its battery may be lost for a long time. Some "raise the millennium". Even causing a lot of loss or extremely affected, so long-term UPS uninterruptible power supply to regularly conduct artificial forces, not only can activate the battery, but also verify that the UPS does not intermittent power supply is in normal state, and The operator can be familiar with the use of the UPS power supply system.
5.ups Restore charging immediately after use, even if the battery is restored to normal. The charging method is: the constant voltage is 2.35 ~ 2.40V, which limits the initial current must not exceed 0.25 C5A, in a 25 ° C environment, the full-discussed battery takes 18 to 24 hours. If the electric can be finished, it can be based on the continuation of the current.
6. If the UPS battery is non-maintained, the specific gravity and the amount of electro-hydraulic amount of the solution are often checked, and the electrolyte or distilled water is added.
7.ups In use, check once a month, and a single battery’s floating voltage is below 2.20V, the entire set of batteries should be balanced. The method is: at a 25 ± 5 ° C environment, the initial current should not exceed 0.25 C5A, and the constant voltage is 2.35 ~ 2.40V, and the fillet is 24 to 48 hours.
8. If the user configures the long delay battery pack, the outer assembly should have constant voltage and constant current function at the same time, and there should be only a charger having only a constant voltage function to avoid affecting the battery life.
9. The distance from the outer battery pack to the UPS should be as short as possible. The area of ??the wire should be as large to increase the conductive amount, reduce the electricity loss on the line, especially when the large current is working, is not overlooked. .
10. Wipe the battery often use a soft rag to keep the battery surface clean and control the dust through the battery’s gap into the electrolyte electrolyte in the electrolyte of the battery, causing the battery to deteriorate.
